Press News Service PhotoRoger Rapoport owns RDR Books, an independent publishing company based in Muskegon. He is embroiled in a lawsuit over publication of the "Harry Potter Lexicon," written by former Byron Center Christian Schools librarian Steve Vander Ark.

He knows the David-and-Goliath comparison.

He understands the role he plays as the underdog in an international fight over publishing rights, pitting RDR Books, his independent firm in Muskegon, against none other than super-celebrity and billionaire author J.K. Rowling of "Harry Potter" fame and fortune.

Still, Roger Rapoport remains undaunted.

"I'd say the intimidation factor is zero," he says.

Even as he awaits the decision -- possibly coming as soon as today -- whether RDR Books can publish a 400-page lexicon or reference book about Harry Potter, Rapoport is philosophical on the issue. And even hopeful-sounding.
